Interesting designs for Rescue Robots – Part 1

Robot rescue is one, if not even the one, upcoming field for robotics. It is not new, but at present many teams and projects around the world are showing up with new ideas and solutions (e.g. NIFTi, CRASAR). So I will start to collect a few interesting approaches, and present them here on RoboBlog.

So our first candidate is the „Bari-bari II“ robot. It is developed by the Tokyo institute of technology and designed to help rescue workers by lifting heavy boulders / plates.

The capabilities are shown in the following video:

The interesting point is not that the robot can lift heavy material. That can be performed by many robots. The most robot systems that can lift material make usage of either a physical manipulator (hand or arm like) or of a blade (like we have presented earlier on this Blog: RoboPlow). But as fare as i know there is not a single one that is designed i such a way that the hole system itself if part of the lifting unit.

By side of all enthusiasm, some questions are still open:

The „Bari-bari II“ is presented as a tool to crawl under a plat or similar stuff. To do so it makes some maneuvers of lifting and singe off. What is about preventing against more collapses?

If there is now a victim below the plate, he or she will also fell the pressure of the lifting and singing. But as fare as i know, this is not wise. Victims, which are stuck should only be moved as much as needed and you shout never remove the pressure from him or here if you can not eminently support him/here by medicine. During the suck time the blood can often not circulate freely. This causes clumps of blood component. If the pressure is released the blood starts to circulate freely trow the whole body and the clumps can jam haemals. This can causes thrombosis which can lead up to death.
